Description
Technical field
The present invention relates to engineering plastics technical field, more particularly to a kind of grid resin and preparation method thereof.
Background technology
Resin flase floor is that one kind glass fibre makees reinforcing material, and unsaturated polyester resin is matrix, by special
A kind of board-like material with many spaces being combined is processed, resin flase floor can be used as structural material, may be used as
The screen cloth filtered to liquid or powdered substance.Meanwhile in order to avoid liquid or powder and resin during filtering
Larger rubbing action occurs for flase floor, so also needing to be lifted the glossiness of resin flase floor, therefore, manufacturing enterprise can be at it
PET resin is added in the matrix of unsaturated polyester resin new grid resin is made.Because PET resin molecular structure is highly right
Claim, there is certain crystalline orientation ability, so with higher film forming and become second nature, and it has good optical property
And weatherability.In addition, PET resin has excellent abrasion performance frictional property and dimensional stability, electrical insulating property and impermeable, matter
The features such as light, high in machining efficiency is measured, therefore, it has very big change for the overall performance of grid resin.
However, because resin flase floor is in long-term filter process in reality, also suffer from that material is different degrees of to be rushed
The effect of hitting etc., thus, different degrees of bending and deformation will occurs in it, so as to substantially reduce the use of resin flase floor
Life-span.
The content of the invention
It is not easy grid resin of deformation and preparation method thereof by force it is an object of the invention to provide a kind of pliability.
The present invention above-mentioned purpose technical scheme is that：
A kind of grid resin, including component A, B component and component C, by it is following according to the mass fraction：
Component A：Propane diols 13~14, benzoic acid 1.4~1.6, PET30~33, antioxidant 0.015~0.025；
B component：Methyl methacrylate 1.5~2.5, cis-butenedioic anhydride 22~24, vinylacetate 11~12.5, fire retardant 0.015~
0.025；

Component C：Styrene 16.64；Initiator 0.02.
Propane diols is good antifreezing agent and plasticizer, so as to its can effectively the freezing tolerance of enhanced grid resin and
Pliability, it is avoided at low temperatures by the possibility of bursting by freezing.Also, it is also a kind of lubricant, in processing reaction
During can effectively improve the mobile performances of all materials, so as to contribute to material to be sufficiently mixed.
Benzoic acid is a kind of efficient plasticizer, so, it is mixed with grid resin melting can effectively improve lattice
The pliability of grid resin.
Methyl methacrylate during reaction can polymerisation generation polymethyl methacrylate, i.e., organic glass
Glass.There is transparency height, the characteristic that quality is strong, mechanical strength is big due to rear polymethyl methacrylate is made, so it can
The anti-extrusion ability of enhanced grid resin, so as to greatly reduce the possibility of grid resin deformation.
In addition, styrene itself can not only be polymerize, polystyrene is formed, and polystyrene has nontoxic, nothing
The characteristic of evil and water white transparency, its light transmittance can reach more than 90%, the printing opacity energy for being advantageous to improve grid resin so as to it
Power, and a glass transition temperature is relatively high, so also reducing the deformation possibility of resin flase floor to a certain extent.
Secondly, cis-butenedioic anhydride and styrene can also carry out a certain degree of polymerisation generation SAM resins in kettle is diluted, its
With excellent mechanics and electric property and high-temperature stability, so as to further increase the high temperature resistant for improving grid resin
And the ability of the anti-deformation of resistance to compression.
Preferably, the antioxidant in component A is 3,5- di-tert-butyl-4-hydroxybenzoic acids and its derivative.
3,5- di-t-butyl -4-4- hydroxybenzoic acids, are not only a kind of antioxidant, improve the ageing-resistant of grid resin
Ability, the service life of product made of grid resin can be extended.Meanwhile contain 3,5- di-t-butyl -4-4- hydroxy benzenes knots
The compound of structure also has anti-inflammatory, antiviral and antineoplastic action, thus, material filtering of this kind of grid resin to foodstuff
After crossing, food will carry part 3,5- di-t-butyl -4-4- hydroxybenzoic acids, so as to user in certain degree
Health also have very big beneficial effect.
Preferably, the fire retardant in B component is nitrogenated flame retardant.
Preferably, the nitrogenated flame retardant is the mixture of melamine and pentaerythrite.
Nitrogen combustion inhibitor is added in grid resin, and this kind of nitrogen combustion inhibitor is the mixture of melamine and pentaerythrite,
Due to melamine when being thermally decomposed it is caused be CO2, N2 and NH2 without producing halide, therefore be environment friend
The fire retardant of good property, meanwhile, and pentaerythrite mixes the heat endurance that can improve melamine with melamine, so as to significantly
With improving grid resin flame retardant effect.
Furthermore pentaerythrite is also a kind of efficiently plasticizer, so as to which it is also beneficial to the pliability of raising grid resin,
And then be advantageous to improve the pliability of whole grid resin, reduce the possibility of its compression deformation.
Preferably, the initiator of component C is AIBN.
AIBN is efficient initiator, and dissociative reaction can easily occur for its molecule, forms very high point of activation energy
Son, so as to promote each polymerized monomer to carry out rapidly polymerisation, so as to substantially increase the preparation efficiency of whole grid resin.
A kind of preparation method of grid resin, comprises the following steps：
S1, the component C for weighing by mass fraction requirement respective quality are put into dilution kettle, and ensure that temperature is normal temperature state,
Crawl opens stirring, until stirring；
S2, weigh corresponding B component by mass fraction requirement and put into reactor, start to warm up to 120-140 DEG C, and be incubated anti-
Answer 3~4 hours；
S3, after the completion for the treatment of S2, control and evaporate 100-105 DEG C of a temperature, treat that temperature of charge rises to 215 DEG C；
S4, the temperature for keeping S3, question response to acid number drop to below 3mKOH/g, reactor are carried out to be cooled to 190 DEG C of processing；
S5, after the completion for the treatment of S4 cooling, the component A that respective quality is weighed by mass fraction requirement is put into reactor, heating
To 203-206 DEG C：
S6, treat that the material acid number of reactor in S5 is less than 43mKOH/g, Cone ＆ Plate viscosity is carried out at 1.95~2.05 (125 DEG C)
Vacuumize reaction；
